Bulgaria has an ancient (189 pre-dreadnought that ought to be replaced or retired.

Here is what I'm thinking of replacing her with: a baaaby flattop.

*Watches the Romanians panic and try to build their own to counter.*

I designed two versions, one with bulges and one without. The ship itself can carry 44 aircraft based on dimensions, with the bulged version being able to take 38 and the unbulged version 33. Not entirely coincidentally I purchased 18 dive-bombers fitted with arrestor hooks, as a "just in case" if I decide she's worth the trouble to build.

The hull dimensions are based off the Turkish Ankara-class light cruisers, which I'm probably going to build to replace my High Seas Fleet vintage "cruisers". (Why in the world Bulgaria got those cruisers is a mystery, because they would have been ancient in WWI, let alone in 1933 when they were purchased...)

So, opinions? A good use of my limited materials, or a waste of time?

I was actualy thinking of doing the same thing (Im still trying to talk myself out of it)

Well frankly unless you intend to get some colonies I don´t see the point with a CVL in the Black sea

I'd have to agree with Vukovlad, Turkey doesn't even have a need for a CVL at the moment as she doesn't have any territorys that need a projection force to protect supply lines.

I think Bulgaria is already heading down the right path by ordering several CL's which could protect supply lines to Russia. A floatplane cruiser might be possible though, an Ankara type with floatplane facility's aft instead of a third triple turret.

Contribution to an allied fleet? im not to sure on the why, I can give all the why nots. Example you are fighting Russia, your fleet is basicly Hosed anyway BB CVL CL DD dosnt realy matter they have more. (Basicly the same situation im in with Italy) anyone realy has to come to you bringing them in range of land based aircraft, and small fast ships.

My plan was for more of a Hybrid.

Hm. Will redesign along these lines, then.

Thats exactly what I just preposed as well, a hybrid cruiser. Almost certainly Russia will be the big source of raw materials, iron ore and oil so thats the only real soft spot for Bulgaria naval wise.

There are only three other nations in the black sea, Turkey, Byzantium and Romania. Only one of those nations is a potential threat. Russia isn't worth even considering as an enemy, a David vs. Goliath on steroids in full body armour and why make an enemy out of your biggest supply basket?

A floatplane cruiser would give you the eyes to see any potential Romanian threats developing against convoy's, potentially even against subs.

True, I guess it would be a bit like the OTL Swedish cruiser Gotland...

Exactly, I've given some thought to this type of ship as well for advanced scouting purposes. Its good to know where and how large the enemy force is so the decision between "Fight or flight" can be made much easier.

I won´t even go for Gotland. Just cancel the idea you need anything above 4000ts. There is no need for airborne elements if you have some recce squadrons based on land.

I´d build/buy two modern 4000ts CLs as flotilla leaders and flag ships and add a flotilla of DDs for each to lead. Then I´d focuse on mine warfare, getting me one or two purpose build minelayers and several flotillas of multi-purpose minesweepers/escorts like the OTL German M-classes. Add a floatilla of coastal subs and several floatillas consisting of 100ts coastal minesweepers (like OTL German R-class) and S-Boats and you´ll have your fleet.

If you need something more exciting (but less effective) you could also lay down/buy a 4000ts-6000ts CDS but I think you´d be better off with the CLs.

Small carriers have severe limits on their usefulness. This one is like a smaller Ryujo. Stability and space are the main problems. For a reasonably useful ship, a single hangar design with large freeboard is probably best. But the aircraft complement will probably be around 20 at the very most. Maybe 10 if we go from Hermes

I revisited this concept since Romania seems set on pursuing a light carrier, whereas I've talked myself out of it. Here's my response: build a third Bulgarian Danube-class light cruiser, replacing the aft turret with gear for more aircraft.

The alternate plan may be to build two 3,000-ton destroyer leaders or built 3000t of minelayers every quarter

I revisited this concept since Romania seems set on pursuing a light carrier, whereas I've talked myself out of it.

Im going to pursue a light carrier in1945 however until then my naval build plans are to replace my old austrian CLs, as well as replace my old destroyers, and build some submarines. Should Russia decide to build a cruiser killer, I shall probably respond with a small BC (around 25000) 12 in guns. Also, the dive/torpedo bombers are for land based squadrons, not for use on carriers.

This is why I am building a fleet of subchasers.

Not sure if those planes are in scale. They look a bit small, though.

I doubt you can store any planes below deck on her stern. There´s not enough hull volume, methinks, due to her hull form. I also think you´ll need the room for crew quarters because there is not much space elsewhere.

Anyway, should you go ahead with the idea - why do you need scuttles when there are hangars?

to hunt down cruisers that only go one knot faster than the reconstructed Sevastopol? And how would a BC with 12" guns help against a ship well-armored against 12" guns and mounting 15" guns?

I agree with Hoo, a Tromp style ship is also more expendable.

Cheers,

I think the flattop is probably not needed at this time.
However, relying on land-based aerial recon is limiting as well. So a floatplane cruiser- I'm thinking more along the lines of Tone would be a reasonable first filler.

One the concept of allied force.... I don't dismiss a CVL or BCL once you have your light units in order- though defining the OPFOR they match against is important. For a CVL I would likely take the armored carrier route, with a large fighter contingent. However, as you identify long term strategic partnerships, you can build your fleet to enhance it's attractiveness as an allied force.

Look at the recent French-Anglo accord, that freed the French from the channel- one could assume resp. for the Black Sea routes of another, or send units to physically aid them.

I don't see the point in carriers, or seaplane cruisers, for either Rumania or Bulgaria. Land-based aircraft will dominate the Black Sea, there's no reason to try to fit a carrier onto that body of water (just like there's little to no reason to do so in the Baltic).
